Finger Limes  These rare, gherkin-size beauties charm with their elegant nickname (&quot;caviar limes”) and an incredible texture: Split one open lengthwise and spoon out a few pearls. As with caviar, the tiny beads inside pop in your mouth, releasing a splash of bright, tart juice. Dazzle guests by using them as garnishes on ceviches, crudos, cocktails or your best Key lime pie. $32.95
